What technologies are needed for mini program development?

The technologies required for small program development are: 1. wxml, which is similar to the programming technology of html web pages; 2. wxss, most of which are the same as the original css; 3. js; 4. json, through json controls the upper and lower menu bars and the order of primary and secondary page display.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The goal of WeChat becoming a way of life has been achieved. It can be said that WeChat has become an independent ecological kingdom in the mobile Internet. Now WeChat needs to use mini programs to harvest offline traffic! Whether it is online traffic or offline traffic scenarios, WeChat mini programs are fully attractive to offline retail stores. So what languages do you need to master to develop components for WeChat mini programs?

First, WeChat mini programs wxml

Engineers who have basic programming knowledge will discover that after coming into contact with wxml, in fact, this The programming concept of the language is similar to the programming technology of HTML web pages. After you study for a while, you will know that the technical content required to develop a WeChat applet is not high, it is just the replacement of some tags. Even if you are not familiar with the front-end If you are very good at it, it would be a very good direction to switch to the development of WeChat mini programs.　　

Second, wxss of WeChat applet

　wxss is WeChat’s css. WeChat replaced the css used in web programming with its own development language, wxss; in fact, the main implementation ideas are basically the same as the web development technology. It is also a simple replacement of some tags, most of which are the same as the original css, Basically, it is correct. They are all implemented by calling the same page. However, it can be said that WeChat applet is simpler and more convenient than web development. For example, in two files, as long as index.wxml and index.wxss are If both files are in the same directory at the same time, it will be as simple and fast as writing CSS directly on the web page.

Third, js of WeChat mini program

If you want to develop a WeChat mini program and learn the js of WeChat mini program, you must be proficient in it, as long as you have the basics of html css js Fortunately, I have devoted myself to learning WeChat Mini Program js, and then there will be no problems in front-end development. However, WeChat JS requires effort to learn. You can buy a reference book or understand the API of WeChat Mini Program, which can be quickly to help you get involved in the development queue.

Fourth, json of WeChat mini program

After mastering the above points, what you need to master is json. Simply put, json is the primary and secondary interface of WeChat mini program. Engineers can control the upper and lower menu bars and the order of primary and secondary page display through json. However, it is not used frequently and is only applied in the basic small program framework. However, this also needs to be learned, because every front-end operation except the display type needs to be matched with the back-end, because if you want to make it big It needs to be simplified, because after modifying the code, what is searched in the mini program is the version after it is online, that is, it is displayed after WeChat review after we submit it. After modifying the source code, it needs to be submitted to the WeChat public for review. Platform - Mini program management platform. Users can only see your modifications after passing the review. Therefore, in order to avoid this trouble, you must learn to develop back-end technology and link it with the front-end to communicate with each other.

In fact, the mini program is similar to the H5 surface. It provides a view layer description language. You need to master WXML and WXSS and the logic layer framework based on JavaScript. Here wxml is equivalent to html and wxss is equivalent to css.
